Choosing LED lighting without costly mistakes: a practical guide for every room

LED lighting is economical to run, takes up little space and is available for almost any application. However, making the wrong choice can quickly result in uncomfortably bright light, a short lifespan or complicated installation. A cabinet light, for example, is not automatically suitable as a bedside light, while a decorative wall light cannot replace focused task lighting.

In this guide, you’ll discover what to look for when choosing lighting for the kitchen, bedroom, hallway, bathroom, gaming room or studio. We’ll then highlight several products suited to different uses.

Three common LED lighting pitfalls

1. Looking only at wattage

Wattage mainly indicates how much electricity a lamp uses. It does not directly tell you how much light you’ll get. That’s why you should also check the number of lumens. A low-wattage lamp may provide enough light for creating an atmosphere, but not enough light above a worktop.

2. Confusing colour temperature with brightness

Colour temperature is expressed in kelvin (K):

  • 2,200–3,200 K: extra warm to warm light, suitable for ambient lighting or the bedroom.
  • 4,000–5,000 K: more neutral light for the kitchen, hallway or workspace.
  • 6,500 K and above: cool white light, mainly intended for clear task lighting.

A higher colour temperature does not automatically mean that the lamp is more powerful. Also check whether the lamp is dimmable if you want to adjust the brightness.

3. Underestimating installation and power requirements

A cordless rechargeable LED lamp is flexible, but needs charging regularly. Battery-powered lighting is useful in places without a socket, but you’ll need spare batteries. A wall light with a fixed connection provides a permanent solution, but requires safe installation when connected to 220–240V. If you’re unsure, it’s best to have it installed by a qualified electrician.

Important specifications to consider before buying

Motion sensor and positioning

A cabinet light with a motion sensor is practical in a wardrobe, pantry or dark hallway. Pay attention to the detection range and how the lamp is installed. According to the product information, the two ultra-thin cabinet lights in this selection have a PIR range of 3 to 5 metres, magnetic or adhesive installation and a rechargeable 1,100 mAh battery.

Before installation, check:

  • whether the sensor is constantly detecting movement;
  • whether the lamp is bright enough for the space;
  • whether the adhesive strip is suitable for the surface;
  • whether the lamp needs protection against moisture.

Size and light distribution

Measure the space before ordering. A 40 cm lamp will not fit inside every kitchen cabinet, while a large wall light can make a narrow hallway look cluttered. Also consider the direction of the light. An adjustable wall light can direct light upwards, downwards or to the side. This is useful for accent lighting, but may not always provide enough light as the main source.

Safety and intended environment

For bathrooms and other damp areas, a suitable protection rating, such as the appropriate IP classification, is important. Only use a product in the environment for which the manufacturer has approved it. For example, not all the Ulanzi video lights in this selection are water-resistant; the LM18 is listed as IPX5 rainproof, but it must not be immersed for extended periods.

For fixed lighting, also check:

  • the voltage;
  • the type of fitting, such as E14 or E27;
  • the maximum wattage;
  • whether the light source is included;
  • whether the product is intended for indoor or outdoor use.

Frequently asked questions about LED lighting

How much electricity does LED lighting use?

Consumption depends on the wattage and the number of hours the lamp is on. A 5-watt lamp that is switched on for four hours a day uses less energy than a 10-watt lamp that is on for the same amount of time. To calculate running costs, look at the wattage, the number of hours per day and your electricity tariff. Lower wattage does not automatically mean that the light output is suitable, so also check the number of lumens.

How long does an LED lamp last?

Lifespan varies by product and operating conditions. Heat, frequent switching, moisture and an unsuitable power supply can affect performance. For lamps with a built-in battery, the charging cycle also plays a role. Do not store rechargeable models completely empty for long periods, and use the recommended USB voltage.

Which LED lighting is suitable for a bedroom?

For a bedroom, warm white colour temperatures of around 2,200–3,200 K are often suitable for ambient lighting. A dimmable LED wall light, filament LED lamp or small battery-powered light offers flexibility. A motion sensor is useful for a wardrobe or nighttime route. In a bathroom, only use lighting whose product information confirms that it is suitable for the intended application and provides the required protection.
